A few versions back, we added code to our products that detects whether the product crashed or was force quit the last time it was run. If we detect this condition, we then check for whether the APE bundle is loaded in our application space. If so, we advise the user accordingly, and recommend that they contact us if the problem persists after removing all third-party system additions and preference panels.

The comments are worth reading as well, if only to reaffirm that APE haxies remain a divisive issue.
